Toxic makeup ingredient profile 4: PEG compounds! “Polyethylene glycols, or PEGs, are petroleum-based compounds that are used to thicken, soften, and gelatinize cosmetics, making them a common ingredient in cream-based products. The main issue with PEGs is that they are often contaminated with ethylene oxide and 1,4-dioxane.
Ethylene oxide is a known human carcinogen, potentially harmful to the nervous system and human development. 1,4-dioxane is a possible human carcinogen that can remain in the environment for long periods of time without degrading.
PEG compounds also enhance the penetration of other ingredients into your skin, which is great if these other ingredients are healthy, but not so much if they are harmful. The number next to PEG indicates how many units of ethylene glycol they comprise, such as PEG-4 or PEG-150. The lower the number, the more easily the product absorbs into your skin.”
